Analog Input (FV, FI)
The Inverter has two types of analog input terminals.
FV-FC terminal: 0 to 10 V (voltage input)
FI-FC terminal: 4 to 20 mA (current input)
Simultaneous inputs are not acceptable. Do not connect the signal lines for inputs FV and FI
simultaneously.
This function is enabled with the frequency reference set to the terminal block (A001 or A201 = 01).
The settings are as follows. (VR: FREQ adjuster)
If AT is not allocated to any of the multi-function input, this means the AT input = OFF in the above
table.
External Frequency (Voltage/Current) Adjustment
External Analog Input (Frequency Reference)
FV-FC terminal: 0 to 10 V (voltage input)
FI-FC terminal: 4 to 20 mA (current input)
Also set an output frequency for the FREQ adjuster on the Digital Operator.
